nvila-walk-130samples

Fine-tuned NVILA-Lite-2B model for blind assistance navigation.

Model Details

• —Base Model: Efficient-Large-Model/NVILA-Lite-2B
• —Training Dataset Size: 130 samples
• —Train: 91
• —Validation: 19
• —Test: 20
• —Training Date: 2025-12-28
• —Run Name: NVILA-2B-Walk-130samples-20251228_200126

Task

Given visual input from a user's forward perspective, generate exactly one short sentence to guide a visually impaired user by:

• —Identifying critical obstacles or landmarks
• —Describing locations using clock directions (12 o'clock is straight ahead)
• —Including relevant details (size, material, distance)
• —Giving one clear action
• —Prioritizing immediate safety

Example Output

"At 1 o'clock direction there is a tree, be careful to avoid it."
